AppleiPhone SE - iOS 10Device maintenanceHow to do a factory reset

When certain applications no longer function properly or if your iPhone SE is very slow, you can reset the device to its factory settings. This will reset the telephone to the settings it had when you first turned it on.

Please note: your iPhone SE may request a security code, which, if necessary, can be found in the instructions of the iPhone SE. Make sure you have them at hand.

If you purchased a used device and do not know the code, you should ask the previous owner for it.

Please note: resetting the device will erase all data and settings on the device. If necessary, make a backup on your computer.
